Z '0 all whom it may concern:

Be it known that l, JEAN MARIE GOUBIER, of Usine de la Chaussee par Aulnay sur Mauldre, Seine and Oise, France, manufacturer, have invented Scraping Devices, of which the following is a full, clear, and exact description.

This invention has for its object a scraping device applicable as carpet-scraper and as scraper-tool.

The said invention is adapted for the production of scraper-carpets or of scraper-tools constituted by independent elements made of rubber and canvas and forming scrapers.

These scraping devices are characterized by elements constituted by means of beads of pneumatic covers of Wheels detached from these covers when the latter are worn off, the beads being still intact and have not been used up to now. i

The elements thus obtained each have a sharp scraping edge and are arranged on a carrier so that the working part should be the acute angle they naturally present, on the side opposite to their cutting off line.

The devices serving to secure these elements on their carrier are constituted by holders the sides of which are suitably drawn together after placing these elements in po sition, so as to thus obtain an energetic clamping of the latter.

The carriers of the said elements are integral with aframe, laid fiatwise if the whole constitutes a scraper-carpet, or which re ceives a socket for a handle if the whole constitutes a scraper-tool. v

If the whole constitutes a scraper-carpet, the latter is very efficient owing: 1 to the sharp edge of the element; 2 to the suppleness of the edge and its elasticity which permits this edge to take the shape of the sole of a boot and to act consequently on all the points of the surface of the said sole without any risk of damaging the latter. It is also to be noted that the carpet. whilstbemg supple and elastic, olfers, from this fact.

As illustrated in the drawing. Figs. 1 to 6. this scraping device comprises elements a made of rubber and canvas and having two plane right angularlv disposed faces and a convex face. one of the plane faces meeting the convex faces .to form a sharp scraping edge. These elements are constituted in; means of beads cut out in a band from the covers of pneumatic tires of wheels when these covers are worn ofllthe heads being still intact and have not been used up to now.

The working part of these elements is the acute or sharp angle a} they naturally prethe line separating them from the remainder of the cover.

These elements, out according to the length of the frame Z), which is preferably of rectangular shape, are secured by holders arranged on wooden or iron cross-bars (Z forming part of this frame. 1

These holders 0 can be formed by means of an iron band or strip suitably folded and secured on the cross-bars (Z by nails, rivets or screws 6. Each of the folds constitute a loop and two consecutive loops form the sides'of the holder 0 provided between them.

The elements a are fitted in the holders 0, as shown in Fig. '5, and then secured by slightly depressing the head of the loops 0 for thus obtaining a clamping of both sides of the holder by raising in the latter on the element, as shown in Fig. 6;

Figs. '?.to 9 illustrate a first form of scraper-tool comprising two elements or scrapers re turned in reverse direction to each other and held by transverse loops 0 forming cross-pieces. Moreover, these strip iron loops are secured by rivets e on holders 0 the ends of which are folded down for forming claws and clamping the sides of the rubber elements a. I

Four similar loops 0 and four holders 0 for instance are provided on the length of the elements and all these loops and holders are connected by the rivets e to two parallel strips f folded down at the ends on the 1311i)- ber elements a.

The whole formed by the loops 0 the holders 0 and the strips f constitutes the baclr of the scraper-tool and this back receives the soclret g for the handle.

This socket constituted by a sheet iron member is shaped in such a manner as to form lugs g which are riveted on the back of the scraper-tool.

The second form of scraper-tool illustrated in Figs. 10 to 12, comprises two juxtaposed elements 0' turned back to back. These two elements are connected together by means of holders 0 forming claws.

Longitudinal strips 7 connect all the hold ers and are secured on the latter by means of rivets e; moreover, the said strips are folded down at their ends and suitably. shaped for constituting a socket g for the handle of the scraper-tool.

F 13 to 15 illustrate a modification of the scraper-tool comprising a single element a. Holders 0 forming claws connect this element, by means of rivets e, to the back constituted by a metal strip f folded down at its ends. The socket g for the handle is formed on the strip l to 21 illustrate'elements a secured by independent holders 0 mounted on the cross-bars (Z of the carrier by means ofa central rlvet e.

' always turned This method of mounting allows of arranging the elem "its a in any direction relatively to the 'flcJQ Z), the acute or sharp angle of these elements being, of course,

on the working side.

The sides of the independent holders are folded down on the two side faces of these elements so as to tightly hold the latter.

The independent holders 0 can be con1- bined with the holders 0, in llig. 19.

be interposed between the said'rubber and canvas elements a and secured in any suit able manner on the carrier.

It is to be understood that the elements a in the frame 5 can be: parallel to the sides of the frame, diagon'alh arranged, form triangles, be corrugated, etc.

The forms, details, accessories, materials and dimensions of this scraping device may be varied without departing thereby from the nature of the invention.
